1760 (aged 28 - 29)
Kaniehtí:io was born in 1731 to Oiá:ner in Kanatahséton and was trained to succeed her from an early age. Throughout her life, Kaniehtí:io would often voice her concerns over the colonists expanding into their territory, despite the village's consensus to stay neutral.
- "There was a woman there, that night. It was she who helped the others to safety. If we could find her, I believe I'll have my answers."
- ―Haytham Kenway.[src]
Prior to the French and Indian War in 1754, Kaniehtí:io was captured and personally escorted to the slaver Silas Thatcher along with other members of her nation. However, on their way to Southgate Fort through Boston, her convoy was attacked by Haytham Kenway and his fellow Templars, who were intent on assassinating Silas as well as freeing the slaves.
On entering the fort, the Templars freed the natives held captive there and Kaniehtí:io led them to safety. While leaving the fort with her people, Kaniehtí:io briefly smiled at Haytham in gratitude.
Later, Haytham decided that Kaniehtí:io would be a vital ally in helping the Templars' search for the precursor site, as members of the First Civilization were considered to be sacred gods by the Kanien'kehá:ka nation. Haytham expected the Kanien'kehá:ka to contact him out of gratitude for rescuing their people, but he heard nothing even after several weeks.
In the winter of 1754, Kaniehtí:io began scouting out Lexington, after learning that Edward Braddock and his troops were posted there, and were attempting to drive her and her people off their lands. Her actions caught the attention of Charles Lee, and led both him and Haytham to seek her out near the town.
However, Kaniehtí:io left her camp moments before they arrived, and soon after the two had caught with her, she escaped into the trees. Haytham was forced to chase her, until she finally stopped to give him a chance to speak. After introducing themselves, Haytham showed her the amulet he had acquired in London. Kaniehtí:io admitted that she had seen similar markings somewhere else, but refused to speak of it, since the location was sacred.
In an effort to gain her trust, Haytham offered to help her kill Braddock, to which Kaniehtí:io agreed but remained suspicious of him. They visited the tavern in Lexington and eavesdropped on several Redcoats, learning that Braddock could be found at Fort St-Mathieu. Upon leaving the tavern, Haytham was stopped by the Redcoats, triggering a bar brawl. After beating the Redcoats, Kaniehtí:io treated a small cut on Haytham's cheek, applying a cloth with alcohol.
Kaniehtí:io later met with Haytham outside Fort St-Mathieu, where Haytham successfully retrieved military plans revealing the route of Braddock's Expedition to Fort Duquesne. Over the the next several months, Kaniehtí:io planned an ambush of the expedition to kill Braddock, while gathering the support of warriors from other native tribes.
On July of 1755, Kaniehtí:io met with Haytham and her Native allies in the Frontier. They attacked the expedition, during which she came to Haytham's aid by tackling and pinning down George Washington. Haytham fatally wounded Braddock and left him for dead.
Fulfilling her end of the agreement, Kaniehtí:io traveled with Haytham to the entrance to the Temple, revealing a painted cave wall; however, the amulet that Haytham had in his possession gathered no results. Seeing his disappointment, Kaniehtí:io explained the story of the cave paintings of their sacred gods. As she held his hand, the two revealed their feelings for one another and shared a kiss; they would later meet again which led to the conception of a son.
Kaniehtí:io raised her son, Ratonhnhaké:ton, in her home village of Kanatahséton. However, due to her actions in the attack of Braddock's Expedition, she was denied the position of becoming Clan Mother herself, having defied Oiá:ner's wishes. Kaniehtí:io also learned the truth that Haytham was a Templar; as a result, she cut her ties with Haytham and began to fear that her son might inherit his malevolent father's ambitions.
Later life and death
- "You will think yourself alone, but know that I will be at your side. Always and forever. I love you."
- ―Kaniehtí:io's last words to her son.
In 1760, one day, Kaniehtí:io allowed her infant son to venture into the forest to play with the other children. The village was later attacked by the soldiers under the orders of George Washington. Kaniehtí:io was trapped beneath a pile of rubble inside a burning hut. Ratonhnhaké:ton, returned but was unable to free and rescue her. Kaniehtí:io shared her final words with her son, until a village elder carried Ratonhnhaké:ton away to safety, reluctantly leaving her to die.
Sometime after George Washington obtained an Apple of Eden and became a tyrannical king, Kaniehtí:io snuck into Washington's fortress and stole his scepter, which housed the Apple. Israel Putnam managed to retrieve the scepter after shooting it off her back as she made her escape. After her failed attempt, she returned to the Frontier, reuniting with her son. The two proceeded through the forest and discovered that King Washington's army of Bluecoats were attacking the frontier in search of Kaniehtí:io.
Kaniehtí:io and Ratonhnhaké:ton fought the Bluecoats while rescuing captured civilians in Concord. As they made their way to Lexington, they came face-to-face with King Washington who warned them that he would have revenge against Kaniehtí:io and destroy their village. While traveling back to Kanatahséton, Kaniehtí:io and Ratonhnhaké:ton met with Teiowí:sonte, who revealed that he was sent by the Clan Mother to collect boughs from the Great Willow Tree, intending to brew the special tea and gain its power. Knowing the risks of the tea, Kaniehtí:io warned and implored her son not to drink it, afraid that it's power would endanger and corrupt him.
Kaniehtí:io returned to village and confronted Oiá:ner, arguing that they should unite and use their strength without the tea. Oiá:ner retorted that they had no choice in order to fight the King's army and blamed Kaniehtí:io for incurring his wrath upon them. Kaniehtí:io left and gave Ratonhnhaké:ton a pair of Hidden Blades, left for him by his father. The village was then attacked by the Bluecoats. After fighting overwhelming numbers, King Washington approached and swiftly killed Kaniehtí:io using the power of the Apple.
After surviving the attack, Ratonhnhaké:ton would later use the tea from the Great Willow, gaining animals powers in order to fight Washington. During his second confrontation with Washington and later during his third sky journey, Ratonhnhaké:ton was met by phantoms of his deceased mother, saddened and condemning him for disobeying her. After the King's defeat, a final vision appeared before Ratonhnhaké:ton, warning him to not take the Apple.
- Kaniehtí:io is the only non-Assassin or Templar to ever be seen performing a Leap of Faith.
- Kaniehtí:io is briefly playable during the Memory Corridor between the end of Haytham's memories and the start of their son's, making her the first woman to be playable in Desmond's ancestry.
- A deleted dialogue from the game shows that Achilles Davenport and Kaniehtí:io were friends. When asked by Connor if she was an Assassin, Achilles simply referred to her as an "ally".
